Tankless Water Heaters

On-demand, tankless, or instant water heaters heat water immediately when it is required, therefore there is no demand for a storage tank. On-demand water heaters are triggered by the flow of water. When there is demand for hot water, a fuel valve opens, firing up the burner. Cold water gets in one side of a coil of copper pipe, which then twists with a heat exchanger that is surrounded by flame, and hot water exits the other side of the heat exchanger.

The efficiency of an on-demand water heater is based on the heat transfer efficiency of the heat exchanger and is 75 to 90 percent effective. One possible issue is pressure drop throughout the heat exchanger which could produce lower flows when more then one source of hot water is made use of.
